Answer:
A. [tex]\text{200 in}^2[/tex].
Step-by-step explanation:
We are asked to find the area of the given face of the composite figure.
We can see that the given face consists two squares whose each side in 10 inches.
[tex]\text{Area of square}=a^2[/tex], where a represents length of each side.
Since the face consists two squares, so area of the given face would be 2 times area of square.
[tex]\text{Area of the given face}=2\times a^2[/tex]
[tex]\text{Area of the given face}=2\times(\text{10 in})^2[/tex]
[tex]\text{Area of the given face}=2\times\text{100 in}^2[/tex]
[tex]\text{Area of the given face}=\text{200 in}^2[/tex]
Therefore, the area of the given face is 200 square inches and option A is the correct choice.
